3G network HD broadcast system

3G network has enough bandwidth channel, mature, reliable network technology, with a stable rate of 2Mbps upload can transmit standard definition programming, stable transmission rate of 10Mbps LAN can transmit high-definition programming, along with modern and efficient coding techniques and the rapid development of video compression technology makes 3G network perfectly suited as a professional real-time video transmission, so as to provide live television a new technical means. Compared with the traditional TV broadcast, 3G can not live Xianzhi time and place real-time reports, low cost, convenient, flexible, mobile, efficient, on-site advantages of easy maintenance. 
 System features: 
 1, the basic no less affected by space constraints. 3G itself is a broadband wireless transmission technology, as long as the camera and 3G wireless transmission equipment connected to the place where a cell phone signal can be broadcast live audio and video. It avoids the TV trucks are transportation, power protection, parking location and parking restrictions with the length of the camera connection and many other defects in the different regions, cities, time to return the same television signal, broadcast live on all over the country. 
 2, without time limit. 3G is a full-time transmission to solve the satellite TV trucks have to apply restrictions on broadcast channels, as long as the signal transmission in a mobile phone connected to the power places, you can implement live broadcasts. 
 3, the investment cost. 3G live communication with the existing wireless carrier networks, broadband operators need to deliver toll traffic on the line. TV and thousands of million cars and expensive compared to the cost of satellite communications can be said to pale into insignificance. 
 4, the device easy to use, need not have directed the scene, subtitles, playback, camera, etc. Some professionals do not need power supply. The use of live 3G equipment, just a journalist, a camera can be competent, all portable devices less than 10 kg. 
 System functions: 
 My company for the 3G network, developed 3G network television broadcast system, in the same image quality conditions, the use of H.264, AVS coding, data compression ratio can be used in the system than the DVD MPEG-2 high 2-3 times MPEG-4 higher than 1.5-2 times. Equipment transport stream bandwidth is: 64kbps ~ 50Mbps, coding rate, high level of system integration, standard definition transmission rate 1.5Mbps, the image resolution of 720x576 format; HD transmission rate 8Mbps, Resolution: 1080p/1080i, to achieve a clear image , system stability, fully meet the high-definition image quality standards. 3G system consists of live television cameras, converters and high-definition decoder, through the 3G network transmission, the receiver outputs SDI and ASI digital video, and live television programs to meet production needs. 
 Used for the different needs of our customers, introduced both man and vehicle systems. System consists of cameras linked to man after the AV (SDI)-3G converter directly to the 3G network; car system from the wireless transmitter to broadcast the camera car, then broadcast vehicles to enter the 3G network. Two systems so that users in emergencies, news interviews, events, events broadcast live in real-time information the first time reported.
